hmm... so I had mine upside-down on the 6 hr trip home, I didn't experience any difference. Signal strengths dropped a tad, but not much...

LOL, that reminds me once I was using a Bluetooth connected SiRFstarIII based GPS receiver with my PC, and I didn't even realize the unit was in my pocket while I was driving. It worked flawlessly during the whole trip .

OK, I know this thread is kind of old, but my Hiacom BT407 GPS is driving me crazy. I cant use it with BT because the bluetooth stack CF uses cant use GPS and Phone (or at least I dont know how too). I see alot of people have the BU-353 and it is fairly low priced and wont break the bank. Although I have a USB to Serial cable for the BT407, it doesnt work because when I come out of hibernation it will act like its not coinnected. I tried Hibernation Trigger, and that doesnt work, so I figure just replace the darn thing.

Do any of you have this issue with the BU-353, with it not showing up after hibernation? Is this unit 100% USB, or is it were it installs as a Serial to USB device. If not I think I will buy it then.

The pharos 360/560 are pretty good too. (SIRFII/SIRFIII and the 360 glows blue )

All USB is serial... so yes it is serial. Never had a problem from resume. Although from what I have seen around here half the time if you have resume issues it is the motherboard. Other time it is the device. So it will fix it if you are lucky, but it wont neccessarily work.

I think maybe this time its this GPS reciever. I do have to have my things plugged into certain USB ports. Like my Sound Blaster has to be on the USB 2.0 PCI CARD Port, so do all my touch panels and pointers. Then everything else goes on the onboard ports, but at least something ports on a port. No matter what port I put this GPS on, it doesnt resume at all.
